Summary

This violation occurs when at least two parts, two sheet symbols, or a combination of these objects - across source schematic sheets in a design - have the same Unique ID associated to them.

Notification

If compiler errors and warnings are enabled for display on the schematic (enabled on the Schematic - Compiler page of the Preferences dialog) an offending object will display a colored squiggle beneath it. A notification is also displayed in the Messages panel in the following format:

Unique Identifiers Errors: found at <Location1> and <Location2>,

where:

Location1is the X,Y coordinates for the first object found with a Unique ID error.

Location2is the X,Y coordinates for the second object found with a Unique ID error.

Recommendation for Resolution

Reset the Unique ID's for the offending objects as required. This can be done at the individual object level, by accessing the object's associated properties dialog and clicking the Reset button next to the field for the Unique ID.
